我有以下格式的文件：

axel localhost> localhost>
mike localhost> STORAGE 298390/512000 (58.279296875%) localhost>
ab localhost> STORAGE 141361/512000 (27.6095703125%) localhost>
fghi localhost> localhost>
abcd localhost> STORAGE 165929/512000 (32.4080078125%) localhost>
lmno localhost> STORAGE 353073/512000 (68.9595703125%) localhost>
nuon localhost> localhost>
spar localhost> STORAGE 203766/512000 (39.798046875%) localhost>
fibo localhost> STORAGE 238204/512000 (46.52421875%) localhost>
nacci localhost> STORAGE 425737/512000 (83.1517578125%) localhost>
seldom localhost> STORAGE 69894/512000 (13.651171875%) localhost>
project localhost> STORAGE 86220/512000 (16.83984375%) localhost>
eccleston localhost> STORAGE 240084/512000 (46.89140625%) localhost>
swan localhost> STORAGE 279522/512000 (54.594140625%) localhost>

这是由listquotain cyradm (Cyrus-imapd) 生成的输出。我有两个问题；

  • 在那些有 的行中localhost> localhost>，第一个单词应该写入另一个文件，并且应该删除该行。
  • 对于其他行，需要删除第二、第三和最后一列。

我将如何实现这个结果？

nacci STORAGE 425737/512000 (83.1517578125%)

到目前为止，我的循环看起来像：

while read thisline; do
    if [ $2 == "localhost>" AND $3 == "localhost>" ];then
        echo $1 >>/root/names.txt
        sed '1d' filename.txt #but this deletes only the first line
    fi

done

试试这个：

awk '/localhost> localhost>/{print $1 >"file2";next}{$2=$3=$NF=""}7' file

这将输出您想要的文本，并为案例生成一个“file2” localhost> localhost>。

没有测试，希望没有错别字。
